in reply to How can i maximize a Tk application on win32 ?

Win32::API's ShowWindow provides access to the Win32 native API function which does this.

I might suggest the Win32Util module; it has a maximize function which conveniently tries to maximize in one of two ways: using ShowWindow if Win32::API is installed, or, as a fallback, resizing the window to the screen size.
